A support structure for supporting a display panel includes a rotatable base, a first supporting assembly, a second supporting assembly, and a connecting portion. The first supporting assembly includes a first sleeve and a first connector moveably coupled to the first sleeve along a first direction. The first sleeve is fixed to the rotatable base. The second supporting assembly includes a second sleeve and a second connector moveably coupled to the second sleeve along a second direction. The second direction is perpendicular to the first direction. The second connector is slidably coupled to the display panel along a third direction. The third direction is perpendicular to a plane cooperatively defined by the first direction and the second direction. The connecting portion fixedly connects the first connector to the second sleeve. A display panel using the support structure is also provided.
